The following are the reasons and solutions to these problems. 

Reason 1: Blocked Oil Filter

A blocked oil filter can cause a ticking noise in the Ford  F-150. When the oil filter is clogged, it restricts the flow of oil in the engine, leading to insufficient lubrication. This can result in metal components rubbing against each other, causing a ticking sound.

Diagnosis: Check the Oil Filter

There are no certain procedures to know the oil filter is clogged unless removing it. However, there are certain signs that indicate the Ford F-150’s oil filter is clogged. Those signs are- 

  • Oil pressure warning symbol on the dashboard
  • Louder engine noise at idle or during acceleration
  • Stalling engine
  • Oil leaks under your vehicle

If you observe these signs in your vehicle then you need to remove the oil filter to inspect it. Let’s go through the step-by-step process of removing and inspecting the oil filter in a Ford F150. Before we begin, make sure you have the following tools:

  • 16mm socket (for the oil pan drain bolt)
  • Cardboard and a catch basin (to collect the drained oil)
  • Rags or shop towels
  • Channel locks or an oil filter wrench

Warning: Turn off the engine completely and wait for it to cool down.

Step 1: Prepare for oil drainage

Start by removing the oil pan drain bolt, located underneath the engine compartment of the vehicle. Use a 16mm socket to loosen and remove the bolt. Place cardboard on the ground and position the catch basin beneath the oil pan to collect the draining oil. Clean the oil pan drain bolt with a rag.

Step 2: Inspect the oil pan and drain bolt

While the oil is draining, take a moment to inspect the oil pan and the washer attached to the drain bolt. Ensure that the washer is present and not stuck on the oil pan. Cleaning the drain bolt with a rag will help remove any debris.

Step 3: Replace the oil pan drain bolt

Once the oil has finished draining, replace the clean oil pan drain bolt. Make sure the washer and the rubber o-ring (if present) on the bolt are in good condition. Tighten the bolt according to the specified torque for your F-150. Consult the owner’s manual to find the torque value.

Step 4: Remove the oil filter

Locate the oil filter and position the catch basin beneath it to catch any oil spillage. Oil will likely dribble out during the process. Use channel locks, an oil filter wrench, or any suitable tool to break loose the oil filter. Once loosened, the filter should spin freely. Continue turning it until it comes off completely, being prepared for oil leakage.

Step 5: Inspect the removed oil filter

Inspect the removed oil filter. Ensure that the rubber o-ring attached to the filter comes off with it. If the o-ring remains on the engine, remove it to prevent double o-ringing, which can lead to leaks. Clean the mating surface on the engine where the oil filter attaches.

You can also check it visually, refer to the image below for a further understanding of what a bad oil filter looks like. 

If you find the oil filter is clogged or bad, it’s recommended to replace it. This is because when it gets clogged once, it can’t perform at its best again. Apart from this, the manufacturer recommends changing the oil filter with the oil according to the recommended interval. Here is the oil changing interval: 

  • Conventional oil: It is recommended to change the oil every 3,000-5,000 miles.
  • Synthetic blend oil: It is advised to change the oil every 7,500-10,000 miles.
  • Fully synthetic oil: It is recommended to change the oil every 7,500-10,000 miles.

Solution: Replace the Oil Filter

To replace the Ford F-150 oil filter, follow these steps. 

Tools needed:

Check the oil level using the dipstick, wiping it clean and inserting it fully before removing it again. Ensure the oil level is within the designated range on the dipstick.

Reason 2: Clogged Fuel Filter 

A clogged fuel filter can create a ticking noise in the Ford F-150 as a clogged fuel filter restricts the flow of fuel to the engine. As a result, the engine doesn’t receive enough fuel to run smoothly. This can cause a ticking sound, similar to a clicking noise. It happens because the engine is struggling to get the fuel it needs, which leads to irregular combustion and engine misfires.

We have a complete article with a comprehensive solution to this issue. So, read  Ford F150 fuel filter symptoms for a complete solution. 

Reason 3: Low Transmission Fluid

Friction between metal components can cause a ticking noise in the Ford F-150 transmission system if the fluid level is low. The low fluid level dries the moving part of the transmission and that constricts the rotation. The sound can be louder as it starts to rotate at a higher RPM. 

Diagnosis: Check the Transmission Fluid Level

To check the transmission fluid level in your Ford F-150 follow the steps below. 

Tools needed: 

  • A dipstick 
  • Towel

Step 1: Locate the Transmission Fluid Reservoir

Older models of F-150 have the transmission fluid reservoir under the hood on the passenger side (till 2010). In the newer models, the location of the reservoir may vary. So, refer to the owner’s manual if you don’t find it. 

Step: Open the reservoir cap and check the fluid level

Rotate the fluid reservoir cap counter counterclockwise to remove it. After removing the cap, take a dipstick and make sure it’s completely dry. Before inserting the dipstick into the reservoir wipe it with a towel. 

Then insert the dipstick into the reservoir as deep as you don’t feel complete resistance. Now, remove it and check the oil mark on it. If the mark is below the medium level on the stick, it indicates the transmission fluid level is low and you need to refill it.

Reason 5: Bad Battery

A faulty battery sometimes can create a ticking noise in your Ford F-150 when you start your truck. During starting the engine battery provides the electricity to the starter motor to crank the engine. When the battery is faulty it can’t deliver enough power to the starter motor to crank the engine. As a result, the pinion gear crashes with the flywheel and generates a ticking noise.

Diagnosis: Check the Battery With A Multimeter

Your Ford F-150 battery may be bad if you observe the following symptoms. 

  • Slow engine crank
  • No start, dim lights
  • Flickering dashboard lights
  • Clicking sounds when turning the key

To be sure if the battery is bad you can do a resistance test with a multimeter. The following video is about how to test the battery with a multimeter. 

If the battery is low-charged you need to recharge it. In case of a completely bad battery, you need to replace it.

However, it’s still a good idea to periodically check the charger and battery to ensure everything is working properly.

If you don’t have a battery charger available and the battery fails to start the car, an alternative method is to jump-start the vehicle using jumper cables or a portable jump starter. Here’s how:

Gather the necessary tools: 

  • A set of jumper cables and either a functioning vehicle or a portable jump starter 

Step 1: Position the vehicles

Park the functioning vehicle next to your Ford F150 so that the batteries are close but not touching. Make sure both vehicles are in “Park” or “Neutral” with their engines turned off. Also, ensure that the parking brakes are engaged for safety.

Step 2: Connect the jumper cables

Open the hoods of both vehicles and locate the batteries. Attach one end of the positive (red) jumper cable to the positive terminal of the dead battery. Then, connect the other end of the positive cable to the positive terminal of the functioning battery.

Step 3: Connect the negative cable

Take the negative (black) jumper cable and connect one end to the negative terminal of the functioning battery. Then, connect the other end of the negative cable to a grounded metal surface on your Ford F150. Look for a sturdy metal part away from the battery and any moving parts.

Step 4: Start the functioning vehicle: 

Start the functioning vehicle’s engine and let it run for a few minutes. This allows the battery to transfer some charge to the dead battery.

Step 5: Start the dead vehicle

Now, try starting your Ford F150. If the battery was the main issue, it should start up. If it doesn’t start, you may need to let the functioning vehicle run for a bit longer before attempting to start your truck again.

Once the battery is recharged and the vehicle is running, you can take a moment to clean the battery terminals. This step helps remove any corrosion and prevent future corrosion.

Necessary tools and components to clean the battery terminals:

  • Battery terminal cleaner OR a mixture of baking soda and water
  • An old toothbrush or battery terminal cleaner brush

Step 2: Apply the cleaning solution

Dip an old toothbrush or a battery terminal cleaner brush into the cleaning solution. Gently scrub the battery terminals to remove any corrosion or buildup. Pay attention to both the positive and negative terminals.

Step 3: Rinse and dry

After scrubbing, use a clean cloth or sponge dampened with water to rinse off the cleaning solution. Make sure no residue remains on the battery terminals. Once rinsed, use a dry cloth or paper towel to thoroughly dry the terminals.

Reason 6: Faulty Fuel Injector

The faulty fuel injector also can cause a ticking noise in the Ford F-150 due to improper opening and closing. If the injector opens too early, it causes incorrect combustion. Consequently, the engine makes ticking, clicking, or other unusual noises.

Diagnosis: Check the Fuel Injector With a Multimeter

Here are some certain symptoms in Ford F-150 that indicate the fuel filter is clogged.

  • Reduced engine power
  • Misfires
  • Check engine light turning on
  • Engine stalling immediately after starting
  • Failure to start
  • Hesitation under throttle
  • Rough vibrations

In case of these symptoms, you need to locate and remove the fuel injector to inspect it with a multimeter.  To remove the fuel injector from the Ford F-150 refer to the video below.

After removing the fuel injector follow these steps to check the resistance with a multimeter. This will require a multimeter as well as a pair of leads for the multimeter.

Step 1: Set up your multimeter

Turn on the multimeter and set it to the ohms (Ω) setting. Look for the horseshoe-shaped Omega sign on the multimeter. Set it to 200 ohms.

Step 2: Determine the resistance specification

Find the resistance specification for your fuel injectors. Typically, fuel injectors have a resistance reading of around 16.5 ohms.

Step 3: Test the multimeter

Before testing the fuel injectors, verify that the multimeter is working properly. Connect the two leads together and observe any changes in the reading on the multimeter. It should stabilize at zero ohms.

Step 4: Connect the multimeter leads to the fuel injector

For each fuel injector, lift the tab and press the tab to disconnect the electrical connector. You’ll see two prongs. Connect a lead to each prong of the injector. The color of the leads doesn’t matter.

Step 5: Test each fuel injector

Start with the first injector. Connecting the multimeter leads to the prongs of the injector. Wait for the resistance reading to stabilize. It should ideally read around 16.5 ohms. Repeat this process for each injector, checking if the resistance is within the specified range.

Step 6: Identify any deviating injector

If you notice one injector showing a resistance reading that is 0.5 ohms off from the others, it may indicate a faulty injector. For example, if all the injectors read 16.5 ohms, but one reads 14 ohms, it’s likely that the one with 14 ohms needs to be replaced.

That’s it! Following these steps will help you diagnose a bad fuel injector using a multimeter.

Solution: Replace the Fuel Injector

Replacing the fuel injector is a complicated process. Therefore, it’s recommended to contact a professional automobile mechanic to replace it. However, if you like to do it yourself follow the instructions in the video below.

Reason 7: Leaky Exhaust System 

When an exhaust system in a Ford F150 is leaky, it can make a ticking noise. This happens because gasses escape around the manifold instead of flowing through the exhaust system. Additionally, the ticking sound can be caused by the rapid cooling of the exhaust pipes. 

Diagnosis: Check the Leak With Soapy Water

If the Ford F-150 exhaust system is leaky there will be some signs apart from the ticking noise. Those symptoms are-

  • Water leaks from the exhaust 
  • A strong smell of exhaust fumes 
  • Decreased engine power
  • Reduced fuel efficiency 

In case of these symptoms, you need further diagnosis of the exhaust system to determine whether it is leaky or not. 

Tools needed:

  • A bottle filled with soapy water
  • Shop vacuum with a blowing function

Step 1: Connect the shop vacuum

Locate the blowing side of the shop vacuum and attach the hose to the exhaust securely. This is the side that blows out air.

Step 2: Insert the hose into the tailpipe

Take the end of the hose and carefully insert it into the tailpipe of the Ford F150. Make sure it is inserted securely.

Step 4: Turn on the shop vacuum

Switch on the shop vacuum, activating the blowing function. This will force air through the exhaust system, aiding in the leak detection process.

Step 5: Spray soapy water on the exhaust

Take the bottle filled with soapy water and spray it generously all over the exhaust system. Pay close attention to the joints and areas where leaks are suspected.

Step 6: Observe for signs of leaks

While the shop vacuum is blowing air or after spraying the soapy water, visually inspect the exhaust system. Look for any bubbles forming or hissing sounds coming from the areas where the soapy water was applied. These indicate the presence of a leak.

Step 7: Thoroughly inspect the exhaust system

With the information gathered from Step 6, closely examine the exhaust system for the source of the leak. Check for cracks in the manifold, loose fasteners, or gasket leaks.

If you are still not sure about how to do it, you can refer to the video below for visual instructions. 

Solution: Replace/Repair the Exhaust Manifold

To repair the exhaust manifold leakage visit a professional mechanic shop as it’s hard to perform. The cost of repair may vary depending on the severity of the issue.

The average cost for a Ford F-150 Exhaust Manifold Replacement is between $530 and $614. Labor costs are estimated between $243 and $307 while parts are priced. 

However, if you’re an enthusiast and like to do it yourself, you can refer to the video below.

Reason 8: Bad Serpentine Belt Pulley/Tensioner

A bad serpentine belt, belt connecting pulley, or a bad tensioner can generate a clicking noise in the Ford F-150. If the belt is bad or worn out some parts of the belt can be detached from it, and those parts can contact other components. 

As a result, you can notice a ticking noise. Also, when the tensioner pulley is bad it can’t keep the belt in proper tension, consequently, the belt can become misaligned.  A misaligned belt also makes noise. Apart from this, the faulty serpentine belt pulley or other accessory pulleys that are snaked by the belt can make an unusual noise. 

Diagnosis: Check for Wear And Tension of The Serpentine Belt

To check the wear and tension of the serpentine belt in your Ford F150, you’ll need a few tools: 

  • A flashlight
  • Belt tension gauge 

Once you have these tools ready, you can follow the step-by-step guide below:

Step 1: Locate the serpentine belt 

The Ford F-150 serpentine belt is typically located on the front of the engine under the hood. The best way to recognize the serpentine belt is, it snakes all the accessory pulleys. 

serpentine belt 
Source: F-150 Hub

Step 1: Visual inspection

Using the flashlight, visually inspect the serpentine belt for any signs of wear or damage. Look for cracks, fraying, or glazing on the belt surface. If you notice any of these issues, it’s important to replace the belt. While inspecting, pay close attention to the factory diagram to ensure proper belt installation.

Step 2: Tensioner inspection

Examine the tensioner pulley for any signs of wear or damage. Check if the pulley is wobbling or not rotating smoothly, as this could indicate a faulty tensioner. Additionally, assess the tensioner’s tightness by applying gentle pressure. If the tensioner feels loose, it may require adjustment or replacement.

Step 3: Check the belt tension

To be sure the tensioner pulley is bad you can check the tension of the serpentine belt. Use a tension measurement gauge to know if the belt is on the correct tension. Refer to the video below for the guide on how to measure the belt tension with a tension gauge.

If you have a bad serpentine belt, you should replace it. In case the tensioner pulley is damaged, you must replace it.

Solution: Replace the Serpentine Belt or Tensioner Pulley 

To replace the serpentine belt tensioner pulley follow the steps below:

Tools needed

  • For key tool
  • A 15mm socket
  • A lift jack
  • A ratchet 
  • A 10mm socket
  • A long extension
  • A 3/8-inch ratchet
  • A light source
  • A new tensioner pulley

Step 1: Access the belt tensioner pulley

To access the tensioner pulley, you need to remove the splash shield located underneath the vehicle. If the vehicle is on the ground, get underneath it. If you have access to a lift, use it to raise the vehicle. Locate the white clips on the splash shield and turn them to the left to unlock them. Pull down the splash shield and set it aside.

Step 2: Remove the splash shield

Use the for key tool to remove the push clips that secure the splash shield. Work your way around and remove all the push clips. You can leave a few in if you prefer, but it’s easier to work without the shield hanging down.

Step 3: Remove the serpentine belt 

Use a 15mm socket and a ratchet to turn the tensioner counterclockwise. This action relieves tension on the serpentine belt. With the tensioner turned you can now remove the serpentine belt from the crank pulley and other pulleys. 

Pay attention to how the belt is routed as you’ll need to install the new belt the same way. Make a mental note of the path the belt takes around the water pump, tensioner, crank, alternator, and back to the water pump.

Step 4: Remove the tensioner pulley

Use a 10mm socket and a ratchet to loosen the lower bolt first, then the upper bolt. Be cautious as the tensioner may fall down once the bolts are removed.

Take the old tensioner pulley and compare it with the new one. Ensure that the mounting holes and the pulley itself match perfectly. This step ensures that the new tensioner pulley is compatible with your vehicle.

Step 5: Install the new tensioner pulley

Position the new tensioner pulley in place and start with one bolt in the upper hole. Get it started, but don’t fully tighten it yet. Then, start the other bolt in the lower hole. Again, do not fully tighten it yet. This approach ensures that both bolts are properly aligned.

With both bolts started, use the 10mm socket and ratchet to tighten them securely. Start with the upper bolt, and then tighten the lower bolt. Ensure that the tensioner pulley is firmly attached.

Step 6: Install the serpentine belt 

Now install the serpentine belt in reverse order as you removed it. If you need to replace the serpentine belt, just install a new one in place of the old one. In this case, you need to avoid steps 3 and 4. However, it’s recommended to replace the tensioner pulley with the belt. 

So, if you want to replace both the serpentine belt and tensioner pulley, don’t avoid any step. 

Step 7: Properly tension the belt

After installing the belt, properly tension it by rotating the tensioner pulley. Rotate the tensioner pulley clockwise to tighten it. Refer to the video in step three of the inspection section.

Step 8: Check the alignment with the hand

Double-check the alignment of the belt by running your fingers along it. Make sure it is not sticking up or off a tooth on any of the pulleys.

Step 9: Inspect if the belt working properly

Start the vehicle and let it run for a few seconds, then turn it off. Inspect the belt once again to ensure it is properly seated in all the grooves. If not repeat steps 7 and 8. 

Step 10: Reinstall the splash shield

Finally, reinstall the splash shield by following the reverse order. Make sure the shield is securely fastened.

With this, you have successfully replaced the serpentine belt tensioner pulley on your Ford F150. If you need any parts or further assistance, you can visit an auto parts store or consult a qualified mechanic.

Reason 9: Bad Valve Spring

When a valve spring goes bad in a Ford F-150, it can create noise as valve springs open and close the valves in the engine. And it keeps them in touch with the camshaft, which controls valve timing.

If a valve spring breaks or gets damaged, it can make the valve stay open or closed longer than it should. This leads to a ticking or knocking sound from the engine. You might notice the noise more when the engine is idle or running at low RPMs. A faulty valve spring can also cause power loss and poor fuel economy.

Diagnosis: Test the Compression

There are a few signs except the ticking noise that indicate the valve spring is bad. 

  • Engine misfire 
  • Check engine light comes on 
  • Low compression 

So in case of these symptoms, you can do a compression test to be sure it’s a valve spring issue. The following video has the complete guide on how to do a compression test in Ford F-150.

Solution: Replace the Faulty Valve Spring

Replacing the valve spring is a very hard and complicated process. To replace it most of the critical engine parts need to be removed. It’s almost impossible to replace at home. For this reason, it’s recommended to contact an automobile mechanic to replace it. 

The cost of a Ford F150 valve spring replacement can range from approximately $810 to $1,520. This includes the cost of valve cover removal ($300 to $500), parts cost ($10 to $20 per spring), and labor cost ($500 to $1,000). Please note that these are estimates and the actual cost may vary depending on the factors.

Reason 10: Bad Spark Plug

There are two primary reasons why bad spark plugs can contribute to a ticking noise in a Ford F-150. Firstly, when the spark plugs deteriorate or malfunction, they can lead to engine misfires, resulting in an audible ticking sound. 

The spark plugs play a crucial role in the engine’s functionality by igniting the fuel-air mixture through a high-voltage charge. To ensure smooth engine operation, this process must occur repeatedly and rapidly. When spark plugs fail to do this it causes a misfire and ticking noise. 

Secondly, it’s possible for vibrations and noise to be produced if spark plugs are not tightened correctly. In more severe cases, improper tightening can lead to the spark plug being expelled from the cylinder head. Consequently, a tapping or knocking noise comes from the engine, and potentially engine misfires.

Diagnosis: Test the Spark Plug With a Multimeter

We have a complete article on bad spark plugs and engine misfires. So, for the complete guide regarding this issue read Ford F150 Multiple Cylinder Misfire.

Reason 11: Faulty Valve Lifter

The valve lifter is connected to the camshaft and is responsible for opening and closing the valve. If it gets bad or worn out then it can keep the valve open or close longer than the usual scenario in Ford F-150. Also, it can also cause a misting during the opening and closing of the valve. As a result of this ticking sound coming from the engine compartment. 

Diagnosis: Test the Compression of the Engine

Here are some signs of a bad valve lifter besides the ticking noise in the Ford F-150. 

  • Low oil pressure 
  • Poor engine performance 
  • Check the engine light on  

If you find these symptoms in your Ford F-150, you need further diagnosis of the lifter. Low compression in the engine is an indication of a bad valve lifter. So do a compression test to know if the valve lifter is bad. Simply follow the video in the compression test segment for this. In case of a bad valve lifter, you need to replace it.

Solution: Replace the Valve Lifter

The valve lifter replacement is a highly technical process. To do this the main engine compartment needs to be disassembled. For this reason, it’s advisable to contact an automobile expert to replace this. 

The cost of replacing a valve lifter in a Ford F150 can range from $46.99 to $100.95 for the parts, and the labor cost can vary between $650 and $2500, with an average of $888. 

Reason For Ford F150 Under The Dash Ticking Noise

There is a reason it makes a ticking noise under the dash. Have a quick look at the table below for an overview of those factors.

Reasons DiagnosisSolution
Uncalibrated Heater Control ModuleInspect the actuator and calibrationRecalibrate the heater control module/ replace the blend door actuator motor

Now, let’s discuss this problem elaborately. 

Uncalibrated Heater Control Module 

An uncalibrated heater control module can cause a ticking noise under the dash of a Ford F150. The heater control module is responsible for regulating the temperature of the air that comes out of the vents. If this module is not calibrated correctly, it can lead to a malfunction in the blend door stepper motor. 

The blend door stepper motor controls the blend door, which is responsible for regulating the temperature of the air coming out of the vents. When the motor malfunctions, it can cause the blend door to move rapidly back and forth, resulting in a clicking noise. This clicking noise can be heard from under the dash, down by the floor in the center.

Diagnosis: Inspect the Actuator and Calibration

Apart from the ticking noise, there will be an erratic temperature reading for a bad heater control module. On the other hand, if the blend door actuator motor is bad there will be an inconsistent airflow. In this case, you need further diagnosis to be sure about the actual issue. Refer to the video below for a visual guide on the diagnosis of an uncalibrated heater control module.

If the heater control module is bad, you need to calibrate it. If the Blend door actuator motor is bad you need to replace the motor. 

Solution: Recalibrate the Heater Control Module/ Replace the Blend Door Actuator Motor

To recalibrate the heat control module you can visit F150 blend door actuator reset. If you need to replace the blend door actuator motor, refer to the video below for the visual guide.

Apart from the aforementioned factors, some other factors might be responsible for the noise in your Ford F-150. Those reasons are-

  • Misaligned radiator fan 
  • Low radiator coolant level 
  • Faulty coolant temperature sensor
  • Faulty thermostat 

We’ve covered these factors in why is my Ford F150 fan so loud?

Is Ford F-150 Clicking Noise Always a Problem? 

The Ford F-150’s clicking noise is not always a problem. It is often caused by the Direct Injection (DI) system, which can be noisy. The DI fuel pump creates a loud ticking sound that corresponds to the engine’s RPM since it is driven by the camshaft. This system is designed to be robust and durable, even though it makes the engine louder. 

Therefore, the clicking noise is a normal part of the F-150’s design and does not necessarily indicate any issues with the engine. Some F-150 owners compare the noise to that of a clattering diesel engine. This whole explanation is covered in my article regarding why my Ford F-150 sounds like a diesel.

FAQ

Is Synthetic Oil Better For Engine Noise?

No, synthetic oil doesn’t cause engine noise. It just makes the noise more noticeable. Conventional oil sticks to pistons better, collecting waste materials and causing oil sludge. Oil sludge muffles engine noise, but also damages performance. Engine noise is caused by natural pits in the engine. If worried, visit our dealership for diagnostics and an oil change.

What Does a Misfiring Engine Sound Like?

When an engine misfires, you hear distinct sounds like popping, sneezing, banging, or backfiring. It happens between 1,500 and 2,500 rpm when unburnt fuel escapes a misfiring cylinder and explodes through the exhaust system. If your car sounds like it’s struggling, it could be a sign of an engine misfire.

Will A Weak Battery Cause A Weak Spark?

Yes, a weak battery can cause a weak spark. A weak battery is not able to start or maintain the engine when the alternator is overloaded. This can lead to a misfire in the engine. To ignite the fuel, the ignition coil needs the right amount of current from the battery. A weak battery might not provide the necessary current to the ignition coil, resulting in a weak spark and potential misfires.

Final Words

The discussion regarding why does my Ford F-150 make a ticking noise is about to end here. Hopefully, you’ve got your desired answer to the query. Remember ticking noise is not always a problem. So, first, you need to be sure about why the noise is coming. If you feel any difficulty during the process, kindly consult with an expert.

Thank you!
